I would like to suggest that the current tab layout is awful. It feels wrong, and gives a terrible user experience. If the tabs were instead laid out neatly beside one another like in google chrome. A user could more easily find there desired tab, and not have to carefully shift through what feels like a unsorted filing cabinet, and instead a modern user experience. I think if you had that as well as tab grouping option to organize your tabs into folders, and even name them to find what you are looking for easier. It would create a user experience that will only draw in new users, and better yet keep them cause the current layout makes me want to uninstall everyday single day.
Please for the love of God change it, or at the very least give me a option to change its layout.
